Garmin Express 4.0.17.0 (Windows 7), Forerunner 910XT
Issue started yesterday 17th April. Not sure when I got the Express upgrade, anyway the syncing looks different. Watch often goes shortly into transfer data, then back after starting actually with the transfer. Progressbar in Express does not go further than 50%, on last (file?) transfer watch hangs at almost 100% for about 5 minutes (timeout?), at the same time Express is at 50%. Watch recovers and ends sync without any message, Express stays at 50% forever.
I have removed device, cleared device data. Same now while adding device.
I'm have beside activity data also weight data, maybe this makes the difference.
Pretty anoying thing, don't think it is related to corrupted data. Cleared history few days ago, first 2 activities synced fine. Hope you find the issue soon...
Thanks
